Access to HC3 version 4 time series for the current day

This service provide HelioClim-3 version 4 time series of satellite-derived solar radiation values for the current day (today). The values are from two different origins/models:

Real time: updated as soon as a new image is available. If you launch the same request 15 min later, the values won't change,

Short-term forecasts: a "persistence model" is applied on the latest irradiation values available to complete the time series until the end of the day. If you launch the same request 15 min later, the values will be modified.

NB: It is possible to use calibration parameters "on-the-fly" to HelioClim-3 request. Please contact us to ask your questions or to receive a quotation.

HC3 Maps in real time

HC3 maps in real time provides 15 min Global Horizontal Irradiation bitmap Maps or Ultra-violet Maps in TIFF format in real time (h-15 min) on a given area, and during daylight time from 3:00 TU to 20:45 UT.

Access to HelioClim-3 version 4 Similarity Forecast data for tomorrow

NB: It is possible to use calibration parameters "on-the-fly" to HelioClim-3 request. Please contact us to ask your questions or to receive a quotation.

Automatic access to HelioClim-1 (1985-2005)

Purchase an annual subscription to automatically access satellite-derived daily solar radiation time series from HelioClim-1 over the horizontal plane, from 1985 up to 2005. NB: an unlimited automatic access to HelioClim-1 is included to all HelioClim-3 annual subscriptions.

Provision of one, a few, or of a large volume of McClear clear sky radiation values over a fix-tilted surface

Ask for time series in CSV format of McClear clear sky values containing all the radiation components over a fix-tilted and the horizontal plane. It can be used as an envelop for monitoring applications. Please specify :

the latitude and longitude values with at least 4 digits after comma,

the time step,

the temporal coverage (from Jan. 2004 onwards),

the plane orientation

NB: McClear radiation values over a horizontal plane and DNI are available for free via this Web interface within the framework of the CAMS project. A small fee is applied to computed the values over a fix-tilted plane. Prices on request.

Calibration of long term HC3 time series using in-situ measurements

In-situ measurements

An expertise is provided to offer you a better knowledge on the quality of your in-situ measurements. A NDA is signed. An example of Quality Check report is included in the Calibration report (see below).

This service delivers a complete report on the quality (QC, which stands for Quality Check) of the in-situ measurements, together with the calibration results of the long term HelioClim-3 (version 5) time series with the short term time series of in-situ measurements.

Data completion

Data completion Service

The routines are able to complete any time series of solar radiation values (satellite-derived or in-situ measurements), as well as the meteorological variables time series containing holes. Please, contact us for a quotation.
